Sinus of Valsalva aneurysm


Sinus of Valsalva aneurysm complications include rupture and mass effect on adjacent cardiac structures causing ventricular outflow tract obstruction, compression of a coronary artery leading to myocardial ischemia, and arrhythmias 1.

This patient's complaint of shortness of breath was likely secondary to the aneurysm causing mass effect and relative right ventricular outflow tract obstruction. In this case, surgical repair was performed.

Sinus of Valsalva aneurysms can be acquired or congenital (Marfan syndrome or Ehlers–Danlos syndrome1. In this case, the cause of her sinus of Valsalva aneurysm is not known.

ECG-gated, contrast-enhanced multisection CT is used to provide better spatial resolution of cardiac structures and detailed anatomy (as used in this case).
